Title: Latest Version Stops Website Working Last modified: August 22, 2016 --- # Latest Version Stops Website Working * [stephenturner](https://wordpress.org/support/users/stephenturner/) * (@stephenturner) * [11 years, 3 months ago](https://wordpress.org/support/topic/latest-version-stops-website-working/) * Hi Guys, a few wordfence versions previous stopped all scans working with the backupbuddy plugin installed, but after removing the backupbuddy plugin, all the websites scanned fine, but since version 5.3.6, most of my websites stopped working completely with the fatal error out of memory error, removing the wordfence plugin got all my websites working again, any ideas. my websites use various plugins, but so far i’ve found over 50 websites, which have stopped working at all until i totally remove wordfence. * any help would be appreciated as i’m sure there must be thousands of other websites doing the same thing, where people may be unaware of, thanks in advance guys… 🙂 * [https://wordpress.org/plugins/wordfence/](https://wordpress.org/plugins/wordfence/) Viewing 11 replies - 1 through 11 (of 11 total) * [Daniel](https://wordpress.org/support/users/dhoffmann/) * (@dhoffmann) * [11 years, 3 months ago](https://wordpress.org/support/topic/latest-version-stops-website-working/#post-5731750) * yes, I have the same problem. I needed to disable it on some sites. It’s not a questions of the memorylimit, on one site it os 512M. 5.3.5 worked fine, but even going crashes them. * Thread Starter [stephenturner](https://wordpress.org/support/users/stephenturner/) * (@stephenturner) * [11 years, 3 months ago](https://wordpress.org/support/topic/latest-version-stops-website-working/#post-5731751) * i’m glad it’s not just me, i got used to uninstalling backupbuddy every time i used it, but now, most of my websites won’t work unless i remove the latest version of wordfence and some only have a few plugins installed. Can anyone from Wordfence shed any light, i think its a case of a false positive again, but the latest version seems too sensitive? * [Daniel](https://wordpress.org/support/users/dhoffmann/) * (@dhoffmann) * [11 years, 3 months ago](https://wordpress.org/support/topic/latest-version-stops-website-working/#post-5731752) * here’s a message of a server (plesk 12, PHP 5.5) with 512M: * Fatal error: Allowed memory size of 268435456 bytes exhausted (tried to allocate 3008981 bytes) in /var/www/vhosts/…/httpdocs/wp-includes/functions.php on line 377 * On the same machine it works on a multisite without any problem. * [mightygeeks](https://wordpress.org/support/users/mightygeeks/) * (@mightygeeks) * [11 years, 3 months ago](https://wordpress.org/support/topic/latest-version-stops-website-working/#post-5731786) * I’m having the same problem.

And it sounds like you got a 500 Internal Server Error. Please check your web server error log or ask your host to do that. Usually when it’s an out of memory issue you’ll just see a white screen, not a 500 error. The 500 usually indicates PHP code issue – perhaps a plugin conflict. * Please enable debugging in Wordfence. Here’s how: * [http://docs.wordfence.com/en/Wordfence_options#Enable_debugging_mode_.28increases_database_load.29](http://docs.wordfence.com/en/Wordfence_options#Enable_debugging_mode_.28increases_database_load.29) * Then do a scan and tell us where it stops or runs out of memory or what issue it encounters. * mightygeeks you asked what we changed.
